Padlocks explained, now to to find out about the lottery wall

The padlocks railing is explained. It's the Peschician version of the fad that started in 2006 in Rome.

"Every week, hundreds of teenage couples visit the Ponte Milvio and testify to their everlasting love by writing their names on a padlock and clipping it to a chain wrapped around two of the bridge's lampposts. They then throw the keys into the Tiber.

The fad was immortalised last year in I Want You, a romantic novel by Federico Moccia, which has just been turned into a film."

Here they throw the keys into the sea below.

The next conundrum is the lottery win. In the town is a news stand and bar called the Mille Cose
On the left of the bar is a marble slab with a list of lottery numbers with one line highlighted and beneath that a marble recreation of the cheque from 1998
63,601,317,316 lira at about 2,000 to the pound when it joined the euro is 31 million pounds.
So who won, where did it go and why the plaque on the wall ?
